- *CrAl- or AlCr-based structural multilayer*

The combination of fcc (Al,Cr)N with hcp (Al,Cr)N was investigated to address the potential for adapting stress, hardness and wear properties [88,96].


The first publication dealt with (AlCr)N and CrN. One aim was to have a "ductile" coating similar to CrN combined with a high oxidation resistance. [19]. A combination with VN was utilised to improve the tribological behaviour at elevated temperatures [152–154]. TiN/(AlCr)N superlattices were deposited by sputtering. The coatings showed both an improved fracture toughness and hardness as compared to the monolayers [71].
